§ Mr. Dellasked the Secretary of State for Social Services what is the reason for the difference of 2 million between the figures given in Table 6 of Command Paper No. 5143 for 1975–76 in respect of Class 1 and Class 2 membership of the National Insurance Scheme and the projected figures for working population in 1975 given on page 721 of the Department of Employment Gazette, August 1971.
§ Mr. DeanThe difference is largely due to the exclusion from the estimates in Table 6 of persons whose earnings are expected to be below the lower earnings limit for contribution liability under the new basic scheme.
